No holiday spread is complete without the sides! Free up some space in your oven this holiday season and make these Cinnamon Twice Baked Sweet Potatoes on your grill. Grilled sweet potato is mashed with butter, cinnamon, and nutmeg before returning to the potato skins and going back on the grill. Go the traditional route and top with marshmallows or a pecan mixture, or boss up and use candied bacon as your topping instead! Whichever you choose, you can't go wrong with this recipe.
